WILLIAM H. GRAY, OF ASHFIELD, MASSACHUSETTS.

' Letters PM..." a'a.10c,355, dated August 16, 1870.

' The Schedule referred tohrthele Letters Patent and making part of thelame To all whom it may concern I Be it known that IJVILLIAM H. GRAY, ofAshfield, in the county of Franklin and State of-Massachusetts,haveiirvented a new and useful Improvement in Hay-Loader;and I do hereby declare that the following is a full clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had-to the line ar-z of fig. 2.

Figure 2 is a top or plan view.

Similar letters of reference indicate corresponding parts.

This machine is moun ed on two wheels, A and B.

On thea-xle, within each of the wheels, is a ratchetw-hcel, with aspring. pawlattached to the wheel, so arranged that the axle is revolvedwith the wheels when the machine is moving forward, and the wheelsrevolve on the axle when a backward movement takes place.

D is a gear-wheel on the axle, by "means of which the cylinders, shafts,and rake are revolved.

E is the frame of the machine, in which the journals of the cylindersand shafts revolve.

F represents the tongue.

G is a front self-adjusting roller, which is attached to the apron guideB.

This apron extends across the machine, and is connected'to and supportedhy-the axle, as seen in fig. 1. v

The pivotsof the roller G revolve in cars, on the guides H, as seen indotted lines.

The wheels of the machine straddle the windrow'ot hay, and the roller Gpresses the hay down.

I is a toothed cylinder, located just in the rear of the roller G.

This"cylinder raises the hay from the ground, and

forces it upward on the guide-apron J, until vit is reached by the teethof the cylinder K.

This cylinder K is revolved by the gear-wheel L on the shaft M, whichgear engages with the wheel L on the end of the cylinder.

The shaft M is supported on the stands N, with a pinion-wheel, 0, on itsopposite end, by which it is driven from the gear-wheel D of the axle.

Both of the toothed cylinders I and K are hollow, and revolve on theends of interior round bars, P 1?,

'whose ends are central with the cylinders, but whose interior portionsare eccentrics, as seen inthe drawing.

The teeth are made with oands 0rrings at their inner ends, which areslipped onto eccentrics,-'while their straight portions are made toenter holes in cylinders, so that, as they are carried around theeccentrics hy the cylinders, they are made to protrude beyond thesurface of the" cylinders in one part of the revolution, and are drawnbackbeneath the surface in the other part.

By this arrangement, the surfaces of those cylinders are made to runclose to the aprons J and R,

l the latter of which is connected with the slat floor or; the elevator,onto which the hay is delivered by the cylinder K.

S is the elevator-frame, which is adjustably connected to the frame E bypivots, so that its opposite end may be elevated or depressed to suitthe condition of the load on the hay-wagon.

' The elevator is held in position by the ratchetbars '1, which arejointed to the frame E, and pass through mortises in the elevator frame,and are pressed outward by thev springs U, sothatthe. ratchet-s teethcatch under the frame, and hold it-in any desired position. V is therevolving rake, formed of bands W, which pass over the pulley X, on theshafts Y Z. The shaft'Y is revolved by means of a gear-wheel, Z, whichengages with the geauwheeiL', on the end of the cylinder K.

a are toothed cross-bars, which connect the bands .W, the teeth of whichcatch the hay as it leaves the cylinder K, and force it upward-on theslatted bottom of the elevator-frame;

e'represents the slats. I

This machine is attached by the tongue to the rear of the'bay -wagon,and passes over the windrows, as before stated, taking the hay cleanfrom the ground, and delivering itonto the wagon, the elevator beingadjusted from time to time during the process of loading, to suit theheight of the hay.

By thisarrangement, the manual labor required is but slight, as thelaborious operation of pitching cured.

Having thus described my invent-ion,

I claim as new' and desire to secure by Letters Patent- 7 v 1. Anapron-guide, H, attached to the shaft 0, and having roller G in carsthereon, arranged as and for the purpose described. e

2, The combination of a self-adjusting roller, G, and apron H, "with thetoothe cylinder 1, and toothed eccentric P, all relatively arranged. asand for the purpose described.

3. The roller G, aprons H J, toothed cylinders I hay is avoided, whilethe greatestexpedition is se-" K, and toothed eccentrics P P,allcorrrbined and relatively arranged asand for the-purpose.described.WILLIAM H. GRAY.
